• Implement a test case to describe the behaviour of a function

Interpreting feedback

• Identify current output and target output in test feedback
• Determine the line an error occurred from some test feedback
• Give an example of why Jest makes tests easier to write than console.assert

Dead Code

• Define what is meant by ‘dead code’
